To all whom it may concern:

Be it kh wn that 1, J HENRY A. GAR.- DINER, a c'tizen of the nited States, res siding at Cll'cago, in the cor. ty of Cook and State of Illiiiois, have inverilted certain new and useful Improvements inOil-Filters; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to a novel construction in an oil filter particularly adapted for the filtration of hydro-carbon h uids and the separation of water therefrom, t e object be-' ing to provide a very sim 1e and eliticient device of tlns character, an consists in the features of construction and combinations of parts hereinafter fully described and claimed.

' cylindrical casing A equipped at its ends wit substantially semi spherical or relatively deeply dished caps B and C. The up er cap B is provided with a central threads open flange preferably of polygonal out-line ing in which one end of a tube D dependin into and disposed centrally of said casing K is secured as is also the deliveryend of a supply pipe E. Disposed adjacent said central opening are'one or more threaded openings, each of which is eds. ted to receive the threaded portion of a SiOlt depending tube or nipple F andthe threaded end of the suction pipe G leading to the carbureter of a hydro carb on engine, said filter being adapt- .ed to feed one or more of the latter, the un used outlets being sealed by means of lugs H. The lower cap C is provided with a arge threaded central 0 ening I receiving the upper end .of a cylin rical member or nipple J equipped between its ends with an annular to re- :I 7. I I} i I l oeive a wrench, a petcock K being mounted in the lower; or discharge end of said nip le.

Secured at its lower end to the upper on of said nipple J is a cylinder Lof very fine mesh wire clot-h of larger diameter than and receiving the lower end'portion of the tube D, said cylinder L being equipped at its upper end m'th an internal fitting telescopica y over said tube D and preventim any liquid passing out of said cylinder except through the eripheral wall thereof. Oll assing into t e casing through said tube 1? is discharged first into aching ring or flange M said cylinder L in which any contained solids are retained, the li uids assi readil l 8 r: y

through the forauiinated wa thereof and in passing slowly toward the outlets becomes separated, the heavier liquid (water) settli at the bottom. Such water together wit ritt articles settl' in said ni le J are g Y H11: P

draine off at intervals through sai petcock K. If desired, the ni ple J may be removed at intervals together with the cylinder L and thoroughly cleansed.

I contemplate providing means for automatically draining oil? water collecting in the bottom of the a' paratus above a given level therein and to t 13 end rovide an outlet N in the cap 0 controlled by a'petcock O and also by a valve P seating on the valve-seat Q formed at the inner end of said outlet, the said valve having a stem movable in a'suit able guide R and secured at its upper end to a float S so'adjusted in weight as to exceed the wei ht or specific gravity of the hydrocarbon liquid and be of less weight than water, said fioat'being thus adapted to be car ied by the water ccfilecting in the bottom of said ap aratus and be raised thereby to unseat saic valve P and permitting a certain quantity of water to be drained off upon opening the said petcock 0. Sand float 1S preferably ring-shaped surrounding said cylinder L and is equipped with a guide pin T passin through an o ening in a projection U secure to the wall 0 the casing A and which as well as the rejection V forms a stopto limit the upward movement of said float. cock 0 is left open the water will be auto matically drained oil at intervals and 1f maintained normally closed the said valve P will serve to prevent the draining off of hy dro-carbon liquid at any time that said pet- II the pet- 2 saunas ,1

ofi the water. The connection of the valve stem with the float is preferably relatively loose so as to permit listing of the float.

I claim as my invention: 4

1. An oil filter comprising a cylindrical casing equip ed at its ends with caps each provided wit 1 a central threaded opening, a,

' provided wit a central threaded opening, a

nipple secured in the central opening or' the lower cap, a foraminated cylinder secured at its lower end to said nipple, a central de-.

pending sup ly pipe secured in the central opening of t e up er cap and entering said foraminated cylin er, the letter be' 9 contracted at its upper end to telcscopics y receive said pipe a petcock at the lower end of saidnipple, and an outlet for liquid in the upper cap, said sup ly pine having connection with a source 0 supp y of oil.

3. A11 oil filter comprising a casing provided at its lower end with a. threaded opening, a nipple equipped at one end with a petcock, fitting said opening and secured therein, a'cylinder of wire cloth and of smaller J5 diameter than said opening secured at its lower end to said nipple, a supply pipe entering said casin at its 0 posite end and terminating within said cylinder, the latter hein contracted at its free end to snugly fit sai n supply pipe, and an outlet for oil above the lower end ortion of said casing.

4.An o5 vided at its lower end with a threaded opening, anipple equipped at one end with a petcock, fitting said opening and secured therein, a cylinder of wire cloth and of smaller diameter than said opening secured at its lower end to said nipple, a supply pe entering 'said i i casing, at its 0 posite end and terminating/ within'said cy lndcr, the latter being con,+ treated at its free end to snugly fit said sup ply ipe, there being an out et for water 1n the ower end portion of said casing, a float in the latter ofless specific gravity than water and greater specific gravity than oil, and'a' valveactuated-thereby and controlling said outlet, there being an outlet for filtered oil above the lower end portionpf said casing. 30

In'testimony whereof, I have si ned my name in the presence of two subscri mg witncsses.
